Abstract

The invention relates to a polyethylene wood plastic material and preparation method thereof. The polyethylene wood plastic material is prepared from the following raw materials in parts by weight: 50-100 parts of wood flour, 1.0-3.0 parts of a coupling agent, 1.0-3.0 parts of paraffin, 50-100 parts of composite wood flour, 1.0-3.0 parts of zinc stearate, 0.1-0.2 part of an antioxidant 1010, 0.05-0.2 part of UV-531, 0.1-0.2 part of an antioxidant 168 and 20-50 parts of PE plastic.

Description

technical field [0001] The invention relates to a wood-plastic material, in particular to a polyethylene wood-plastic material and a preparation method thereof. Background technique [0002] Wood-plastic composite (WPC) is a new type of composite material that has been booming at home and abroad in recent years. It refers to the use of polyethylene (PE), polypropylene (PP) and polyvinyl chloride (PVC) to replace the usual resin adhesive, and more than More than 50% of wood flour, rice husk, straw and other waste plant fibers are mixed into new wood materials, and then processed by extrusion, molding, injection molding and other plastic processing techniques to produce boards or profiles. Mainly used in building materials, furniture, logistics packaging and other industries. The plastic and wood powder are mixed in a certain proportion and then extruded to form a board, which is called an extruded wood-plastic composite board. This kind of material began in the United State...
